The restaurant may be just as good as the original writer proclaims. My comments are on some of the follow-up.
1. Tecate is a border town east of Tiajuana, Baja California. It is the home of the Tecate Brewery. Tecate Beer has a rather cruddy reputation for quality (or lack of it).
2. Almost anyplace that has a Mother's Day Buffet will spike the prices for a captive, desperate, and guilt-ridden audience!! Our local Best-Western Motel complex in SoCal had a decent restaurant in it. On Mother's Day they expanded to one of the major function rooms to be able to handle the crowd, and jacked their Sunday Brunch Buffet price from the usual $12.95 to $32.95 (2000 price) for that holiday. Sons and daughters would gladly pay that ransom to take "Mom" out to get some scambled eggs and roast beef and a plastic cup of Champagne! There really is no alternative, other than actually cooking for Mom at home, and lots of people would not even consider that !
